Judge Gary Burrell QC paid tribute to her four-year Army service in which she had served in Bosnia and Kosova, describing it as 'exemplary.' Apart from a drink driving conviction, she was of previous good character.

Lewin, who has 11 previous convictions for 18 offences, was convicted after denying the same allegation. She was jailed for a total of four years and four months.

Speaking about Steadman, Judge Burrell said: 'He was vulnerable because he was unable to defend himself.

'You could have easily killed him or caused him a permanent brain injury.' Bradbury and Lewin are no longer together.

The court heard Mr Steadman, 45, had also complained to Bradbury earlier in the evening about the level of noise coming from their flat.

Speaking after the trial DC Rory Kemper said: 'Bradbury and Lewin said he had made a sexual pass at Bradbury, which had been upsetting.

'Mr Steadman said the women had become angry because of a noise issue.'
